    The policy can take values of "static" or "dynamic". In case of "static" the virtual CPU cores are requested to be allocated to logical CPU cores according to the rules defined in virtualCpuPinningRules. In case of "dynamic" the allocation of virtual CPU cores to logical CPU cores is decided by the VIM. (e.g.: SMT (Simultaneous Multi-Threading) requirements).

    Specifies the virtualized resource related performance metric to be tracked by the VNFM, e.g. for auto-scaling purposes. The VNFM collects the values of performance metrics identified by this information element from the VIM(s) using one or more locally initiated PM Jobs. These values can be used as inputs to auto-scaling rules

    VNFM determines if this parameter is considered.

    The vendor may provide this information as a guidance for creating PmJobs if needed.

    NOTE: The MANO or NFVI may not support the recommended collectionPeriod based on their functionalities, and can reject the requests based on the recommended collectionPeriod in this case.
